Frost and icy conditions to start this Tuesday, January 16. It will be mainly dry with spells of crisp winter sunshine for most, although it will remain cloudier with outbreaks of rain and some further falls of sleet or snow in the northern half of the province. 

The rain will become patchier through the afternoon, and it will drift further south. Highest temperatures of 3 to 6 degrees in mostly moderate southwest to west winds, fresh at times in the northwest.

TONIGHT: Patchy clouds, along with some light rain and drizzle, will affect the country's southern half overnight. Long clear spells develop further north with isolated rain showers, with sleet and snow possible near northern and northwestern coasts. 

Lowest temperatures of -4 to -1 degrees with a sharp to severe frost and icy stretches forming. A light, northerly, or variable breeze will also allow fog patches or freezing fog to develop.
